Results The US population made 1.3 primary care visits per person in 1994, which accounted for 43.5% of all ambulatory visits to physicians'offices, community health centers, and hospital outpatient departments. Primary care visits per person were 20% lower for Hispanics and 33% lower for black, non-Hispanic persons compared with white, non-Hispanic persons. (...)
